"From the battlefields of Infinity comes a new team to protect Earth," said Marvel.

"With the Avengers light-years away in space, contending with the Builders, and Thanos' marauders ransacking the Earth, doing as they please - who will stand in defense of mankind?"

On Marvel's AR app, an interview with executive editor Tom Brevoort revealed more details of the team.

"During his tenure with the New Avengers, Luke Cage kind of came to be the moral center of the group, of the team," he said.

"While he's now retired from being an active Avenger because of the need to raise his daughter in a safer environment, the call to arms and the catastrophe that is Infinity forces him to get back up off the bench and pull together a bunch of other characters, a bunch of other heroes in the absence of the Avengers to be the Avengers when no-one else can, and Luke's the one character who's got the gravitas and the wherewithal to be able to make this happen."
